Ben Affleck, Jennifer Garner Name Baby Boy Samuel

Proud dad Ben announced via Facebook: "We are happy to announce on February 27, Jennifer gave birth to a healthy baby boy, Samuel Garner Affleck.”

According to US Mag, the spawn is predictably gorgeous, with one friend cooing he’s a “peanut”.

The Hollywood couple already have two daughters; Violet, six, and three-year-old Seraphina, and the new arrival means Ben finally gets his wish of having a son.

Jennifer revealed to US Weekly before her pregnancy last year: "Ben would like a boy, but I don't want another baby right now."

Garner, 39, announced her pregnancy in August but the couple refused to reveal the sex of the child or any name choices, although she confessed her daughters were going for a Disney theme.

She told E! Online: "(They suggested) Donald Duck, Minnie Mouse Affleck, and then they moved on to Peter Pan, Captain Hook, Smee..."

Despite the lack of decent suggestions, the youngsters may have had more of an input than most siblings after Violet helped choose her younger sister's name when her famous parents were at a loss to call her.

Jennifer previously explained: "A week... (after giving birth) we hadn't decided. So we just went with what Violet wanted... and the thing we liked about it was it meant angel in every language.. She gets her way sometimes."
